Transfer costs in a resource transfer system

Abstract

Systems and techniques are provided for a resource transfer system. An instruction to transfer a first quantity of a resource from a first resource pool to a second resource pool may be received. A hold may be placed on a second quantity of the resource in the first resource pool. The held second quantity of the first resource may not be transferred from the first resource pool until the hold is released. Responsive to receiving a message that fulfills a condition on the hold and an instruction to execute the transfer, the hold may be released. A register that is in the first resource pool and is associated with the resource may decremented by the first quantity, and a register that is in the second resource pool and is associated with the resource may be incremented by the first quantity.

 receiving an instruction to transfer a first quantity of a first resource type from a first resource pool to a second resource pool;   placing a hold on a second quantity of the first resource type in the first resource pool to create a held second quantity of the first resource type, wherein the held second quantity of the first resource type cannot be transferred from the first resource pool until the hold is released;   receiving from a trusted system a message that fulfills a condition of the hold, the message comprising a signed message signed by a cryptographic private key of the trusted system;   receiving an instruction to execute the transfer of the first quantity of the first resource type from the first resource pool to the second resource pool; and   responsive to receiving the message that fulfills the condition on the hold and the instruction to execute the transfer, releasing the hold on the held second quantity of the first resource type, decrementing a first register that is in the first resource pool and is associated with the first resource type by a third quantity, incrementing a second register that is in the second resource pool and is associated with the first resource type by the first quantity, and incrementing a third register in a third resource pool by a fourth quantity.

         11 . The method of  claim 1 , wherein releasing the hold on the second quantity of the first resource type, decrementing a first register that is in the first resource pool and is associated with the first resource type by the first quantity, incrementing a second register that is in the second resource pool and is associated with the first resource type by the first quantity, and incrementing a third register in a third resource pool by a fourth quantity, are performed deterministically on receiving the message that fulfills the condition on the hold and the instruction to execute the transfer and cannot be halted. 
     
     
         12 . The method of  claim 1 , wherein the resource type comprises a currency, cryptocurrency, financial instrument, commodity, physical good, specific item or items, or computational resource. 
     
     
         13 . The method of  claim 1 , wherein the sum of the first quantity and the fourth quantity equals the third quantity.
